Let’s visit Numberland” has been scientifically evaluated twice with “kindergarten German type” children (In Germany the children attend kindergarten from the age of 3, until they enter school at the age of 6. The children go on five days a week, either only for the morning or for the entire day).

From 2003 to 2005, Dr. Gerhard Friedrich and school psychologist Horst Munz carried out two trials with 3 to 5+ year olds. The project war funded by the Ministry of education, cultural affairs, and sports of the German state of Baden-Württemberg as well as the Robert-Bosch-Foundation. In 2006, the results were published in a peer-reviewed journal.

From 2005 to 2009 Dr. Sabina Pauen, professor for developmental psychology at the University of Heidelberg, conducted another study with four to five year olds. Both studies involved many children with to some extent severe language problems.

The second study, since it ran over 5 years, also provided broad feedback from primary teachers on the 'Numberland children', many of them from underprivileged families. All teachers confirmed that the children were now much better prepared for year one: knowledge, self-esteem, language, overall motivation.



Description of the study by Friedrich/Munz

During 10 weeks 46 children aged 3 to 5+ traveled to Numberland once a week. Each week they visited one number for approximately 50 to 60 minutes. Whenever suitable, the respective number of the week was picked up during the daily routine (circle time, creative play, sports, meals etc.). The children had access to the material for free play. In parallel, a control group of 46 comparable children carried on with their normal routine and had no access to Numberland. In a second run, this setting was repeated with underprivileged children, many of them having severe language problems and lacking other skills. The charts depict the results of that second run.

Project and control groups were tested before and after the 10 weeks in which the project took place. The tests comprised tasks such as conceiving and building sets of numbers, colors and shapes, remembering numbers, cognition of details, general reasoning powers. Regarding active and passive language skills, the children made a story out of some pictures, were asked what they remembered from a story that had been read out to them, and they had to carry out tasks of differing complexity. The effects of 'Let's visit Numberland' both on math relevant thinking and on language have been tested twice with significant results.
